Hirun En­gi­neer­ing aims to shake up seis­mic mar­ket

Wuhan Hirun En­gi­neer­ing Equip­ment Co Ltd said it is aim­ing to ex­port more bridge and anti-seis­mic prod­ucts, af­ter build­ing its first high-per­for­mance seis­mic test­ing ma­chine ear­lier this year to sim­u­late earth­quake ef­fects.

Hirun, a man­u­fac­turer of bridge bear­ings and seis­mic iso­la­tion prod­ucts, is a wholly owned unit of Wuhan Marine Ma­chin­ery Plant Co Ltd, a ma­jor ship equip­ment sup­plier in China.

“We are up­grad­ing our core tech­nolo­gies as China strives to­ward the goal of in­no­va­tive man­u­fac­tur­ing,” said WMMP Chair­manMa Juy­ong.

“Thede­vel­op­mentofthe­seis­mic test ma­chine marked the first time that we hired highly ex­pe­ri­enced for­eign ex­perts to join the com­pany to in­tro­duce tech­nol­ogy,” he added.

Anti-seis­mic de­vices are in­stalled in build­ings or en­gi­neer­ing projects to neu­tral­ize vi­bra­tions caused by seis­mic events.

The seis­mic test ma­chine was de­vel­oped by a joint lab, newly es­tab­lished by the com­pany and Tongji University, a lead­ing en­gi­neer­ing university in Shang­hai.

“The ca­pac­ity of the lab is on par with top seis­mic ex­per­i­ment labs in the world, such as the SRMD lab of Cal­i­for­nia University in theUnited States and the Euro­pean Cen­ter for Train­ing and Re­search in Earth­quake En­gi­neer­ing’s TREES lab,” saidHirun’s Pres­i­dent Peng Shengli. Ma Juy­ong,

With a max­i­mum ver­ti­cal load of 75,000 kilo new­tons, the ma­chine can sim­u­late real seis­mic con­di­tions on iso­la­tion de­vices, through the ap­pli­ca­tion of big forces and high speeds.

It is able to test the re­li­a­bil­ity of seis­mic iso­la­tion de­vices, in order to pro­vide de­tailed com­pre­hen­sive dy­namic mon­i­tor­ing data for prod­uct de­sign.

“China was not able to carry out high-speed dy­namic load tests for seis­mic iso­la­tion de­vices in ac­cor­dance with the most ad­vanced in­ter­na­tional stan­dards,” Peng said.

“But the com­ple­tion of the test ma­chine has changed the sit­u­a­tion.”

In order to de­velop the ma­chine, Hirun in­vited three Ital­ian ex­perts to guide the re­search three years ago.

“We did that to trans­fer tech­nol­ogy. The test ma­chine was con­structed in order to sat­isfy Euro­pean stan­dards, which are the high­est in the world for seis­mic prod­ucts,” said Agostino Mar­i­oni, a vi­cepres­i­dent atHirun.

“It is nearly im­pos­si­ble for any other coun­try to de­velop such a com­pli­cated ma­chine in such a short time,” said se­nior en­gi­neer Roberto Dalpedri.

“The fast mo­bi­liza­tion of busi­ness know-how, tech­nol­ogy, in­vest­ment and peo­ple can only be re­al­ized in China.”

Marco Banfi, tech­ni­cal di­rec­tor atHirun, said thatChi­nese prod­ucts still faced dif­fi­cul­ties in build­ing a good­name in the in­ter­na­tional mar­ket.

“Over­seas cus­tomers usu­ally feel un­sure when it comes to made-in-China prod­ucts. But, in fact, many Chi­nese com­pa­nies have be­come first class in the world. This needs to be known world­wide,” he said.

The com­pany said it had won a bid to sup­ply seis­mic iso­la­tion prod­ucts to the $4.4 bil­lion Padma Bridge Rail Link Project in Bangladesh, which is be­ing built by China Rail­way Con­struc­tion Corp Ltd. It isChina’s biggest bridge con­struc­tion project be­ing built over­seas so far.

Hirun now ex­ports to 15 coun­tries and re­gions, in­clud­ing In­dia, Turkey, the Mid­dle East, Rus­sia, Ja­pan and Italy.
